Character Counter for ChatGPT

This repository contains a JavaScript script that adds a character counter to the OpenAI ChatGPT interface, helping users to keep track of their input length. It also includes functionality to toggle between character limits for different GPT models and to hide/show the character counter.

Features

• Character Counter: Displays the number of characters typed in the chat box and the maximum allowed characters.
• Toggle GPT Model: Allows users to switch between GPT-3.5 and GPT-4 character limits (4000 and 25000 characters respectively).
• Toggle Counter Visibility: Provides an option to hide or show the character counter.
